History: 2003 Dodge Grand Caravan, 120k+ miles, Car has (since the beginning of the winter) been taking a long time to heat up. It does not heat well when idle. Normally I use antifreeze (no water added) in winter, I added in about 3 cups of antifreeze w/water mix in radiator (because its all I had) and I believed the level was low and w/no heat.
About a week later when starting the engine, I heard high pitch whine. I noticed that the blower was not blowing out heat, and engine temp spiked to High. I added almost a full container of antifreeze (no water). The engine temp still spiked to hot (lite on) and then when going slow or idling went back to 1/2. I turned off the blower and engine heat spiked again. Now engine heat at 1/2 (normal) at all times.
Problem: When I turn on the blower in car for heat, fan works fine, (sometimes it whines), the heat come out full blast but it only lasts for about 15 seconds, then nothing but cold air comes out.
